Method for manufacturing cylindrical battery and groove-forming processing device of cylindrical battery

A method for manufacturing a cylindrical battery includes allowing a cylindrical battery case (5) with a bottom to contain an electrode plate group, carrying out a groove-forming processing on an outside periphery of an opening of the battery case, disposing a sealing plate in the opening of the battery case through a gasket, and crimping and sealing the end of the opening of the battery case. In a groove-forming processing process in which the battery case is rotated and a rotatable groove-forming roller (15) comes into contact with and is gradually pushed into the outside periphery of the opening of the battery case in a state where a core (12) corresponding to the diameter of the opening of the battery case is fitted into the opening of the battery case to support the battery case from the inner peripheral side, a rotational speed is increased in accordance with increase in the diameter of the battery case so that the push-in amount of the groove-forming roller per unit rotation perimeter and per unit of time approximately becomes a certain value even if the size of the diameter of the battery case varies. Thus, a common groove-forming processing device can carry out the groove-forming processing on battery cases of different battery sizes to manufacture cylindrical batteries.

Processing Apparatus and Method of Manufacturing Electron Emission Element and Organic EL Display

Disclosed is a processing apparatus which can realize highly fine batch pattern film formation for a mask, which is significantly increased in weight according to the demand for increasing the size of an object to be processed, whereby leading to a possibility of reduction in the alignment accuracy of a pattern.The processing apparatus 1 which fixes and processes an object to be processed 300 and a mask 200 includes a base 400 on which the object to be processed 300 and the mask 200 are placed. The processing apparatus 1 further includes second fixing means 101 and first fixing means 102. The second fixing means 101 includes a permanent magnet for use in fixing a mask frame 200a of the mask 200 on the base 400. The first fixing means 102 includes a permanent magnet for use in fixing a mask membranous plane 200b of the Mask 200 on the base 400. The second fixing means 101 and the first fixing means 102a, 102b are mechanisms in which each permanent magnet can move the base 400 in a vertical direction.
